MACHINE FORVSEWING ON BUTTONS'.

SPECIFICATION forming part of Letters Patent No. 267,642, dated NovemberI4, 1882.

- Application filed August 28, 1882. (Model.)

of New Jersey, have invented certain new and useful Improvements inMachines for Sewing on Buttons; and I do hereby declare the fol-i lowingto be a full, clear, and exact description of the invention, such aswill enable others skilled in the art to which it pertains to make anduse it, reference being had to the accompanying drawings, which formpart of this specification.

spective of my invention complete.

My invention relates to an improvement in machines for sewing onbuttons; and it consists, first, in the combination of three slidingplates or parts and a connecting-latch or device, whereby two of theplates can be connected together so as "to cause them to move in a lineaccording to the direction in which the eyes in the button extend;second, in a presser-foot provided with a suitable means for holding thebutton, and which presser-foot can be turned backand forth through aquarter of a circle.

The object of my invention is toprovide an attachment forasewing-machine whereby but tons can be sewed upon clothing with greatease and rapidity, and which can be adjusted to buttons of differentsizes.

Figure 1 is a plan view of my invention.

.Figs. 2 and 3 are side elevations taken from opposite sides. 5, 6, 7,8are detail views.

Fig. 4 is an end view. Figs.

Fig. 9 is a per- Fig.10 is a detail view of the presser-foot.

A represents the frame of the sewing-machine, and B the driving-shaft,which is provided with a beveled-pinion,0, for imparting motion to thebevel-wheel D, which is placed upon the lower end of the shortshaft E,which extends through the top of the table and operates thedilferentparts; To the upperend of this short shaft E is secured the camF, which has the screw G passing entirely through it, as shown in Fig.8.This screw is movable back and forth through the cam, and has its headedend to catch in between suitable projections, H, which are secured tothe inner side of the bearing-surface I, which is attached to one sideof the cam by means of a screw. This bearing-surface I consists of acircular piece of metal, which is made adjustable inand out upon thecam, so as to give a greater orv less movement to the different parts,inproportion to the distancebetween the eyes of the button which is beingsewed on. In order to keep this bearing-surface I always in position,there are two studs or projections, J, formed on its inner side, andwhich fit in the corresponding sockets made in the side of the cam, soas to guide the bearing-surface back and forth in its movements. Theseprojections prevent the bearing-surface from getting out of position orbringingany strain to bear upon the head of the screw. The farther apartthe eyes in the 6 I button the farther this bearing-surface is movedoutward, so as to give a longer stroke to the moving parts.

Secured upon the top of the table is the bearing-plate K, which hassuitable dovetailed 7o guides, L, secured upon its top, and in betweenwhich guides moves the plate M. Upon the outer edge of this plateM isformed a suitable bearing,N ,against which the bearin g-surface of thecam strikes as the cam is made to revolve, 7 5

and as the bearing-surface ot' the cam is made to press against thisplate the plate is moved forward in the direction ofthe needle. As soonas the pressure of the cam upon the plateis relieved suitable springs,O, draw the plate back into position again. The guides between whichthis plate moves prevent it from rising upward or having any lateralmovement whatever. Upon the inner'end of this plate is formed a raisedflange, I, and upon one side of this flange is 8 formed a socket, Q,into which the end of the locking-bolt It canbe forced when it isdesired 7 to lock the plate M to the sliding plate S. This sliding plateS also has formed upon its inner end the socket T, through which thebolt two movements-one in a straight line with the plate or slide M, andthe other a movement at right angles to the plate or slide M passes. Thesliding plate S is adapted to have when disconnected therefrom. Theinner end 5 of the sliding plate S is cut away at a suitable angle, soas to correspond with the angle at which the inner end of the plate M iscut, so

that when the slides M and S are connected together they formpractically one, or when which the slide M moves, while its outer end isdovetailed and fits in a correspondinglyshaped groove,'which is made inthe top of the sliding plateT. When the slide S is given a sidewisemovement by the beveled end of the slide M this sliding-plate T. movesendwise with it, as though formedin a single piece. The movements ofthis sliding plate T are controlled by the guiding pieces U, which havetheir edges dovetailed, and which not only prevent the plate T fromhaving any lateral movement, but prevent the plate from being raisedupward.

Upon or'near the center of the slide S is pivoted the presser-foot V,which is hinged or pivoted at its inner end to the revolving plate \V,which is pivoted upon a suitable standard, X, which rises from the topof the slide S. This pivoted plateW is held down in position by suitablecatches, which prevent it from rising upward, but allow it to freelyrevolve. Between the pivoted plate W and the presserfoot is placed asuitable coiled or other spring, which keeps the presser-foot constantlypressed upward when it is left free to move.

Pivoted in the standard X, around which the plate W is placed, is apost, X, which has its upper end slotted, and in which is pivoted thelatch Z. This latch serves to hold the presser-foot carrying the buttonwhich is to be sewed on the garment down in contact with the garment.

To the under side of the presser-foot is secured the perforated disk ofrubber A, which is made to catch hold of the edges of the button whenthe rubber is pressed down over its edges. This rubber serves to pick upthe button, and then to hold it in position while the button is beingsewed on. As this presserfoot is intended to be moved through a portionof a circle the two stops B are provided for the purpose of preventingit from being turned too far around in either direction.

Secured rigidly to the endwise-movin g plate T isthe plate O, whichextends in a line with the slide S, and which serves as one of theguides between which the plate S moves when the slide S is connected tothe slide M by the locking-bolt. Upon this plate 0 is formed a portion,D,'of the socket in which the locking-bolt moves, and in which one endof the locking-bolt is held while looking the bolt of the plate 0. Whilethe locking-bolt is connecting the slide Sandthe plateOtogetherthe slideS is entirely disconnected from the slide M, and then the slide M, as itis moved back and forth, serves only to move the slide S at right anglesto the movement of the slide M. Upon the top of this'plate O is formed araised surface, F, and from this raised surface project the two points1, upon which the button is placed. By having these two points I thebutton is always placed in the proper position, so that when taken up bythe presser-foot the eyes are always in position to have the needle passthrough them. The button having been placed upon theseprojections,thepresser-foot is swung around until it strikes against a stop, B, andthe hole in the rubber comes just over the button. When the presscr-footis pressed this opening through the rubber, where it is "downward thebutton is forced upwardthrough held by frictional contact- Thepresser-foot is V thenswung-back into position in a line with the slideS, and thenby forcing down the latch the button is pressed down inposition upon the garment. When there are only two holes in the buttonthese holes will extend in a straight line with the slide S; but whenthere are'four holes in the button. two of them extend in a straightline and two of them at right angles.

If it is desired to first have the needle carry the thread back andforth through the two eyes which are in a line with the slide S, thelocking-bolt is forced inward, so as to lock the two slides M and Stogether, when the two will operate as though one, and in adirect linewith each other. After the thread has been carried through these holes asufficient number of times the locking-bolt is moved so as to connectthe slide S with the plate 0, when the slide S at once begins to move atright angles to the slide M, and then the needle is carried through thetwo holes which arein a line with the sliding plate T. It will readilybe seen that the two movements are given to the slide S for the purposeof enabling the needle to sew on buttons having either two or fourholes.

The sidewise movement of the slide S is imparted in one direction by theforward movement of the slide M, and the return-movement of the slide iscaused by a suitable spring, 0, which has one of its ends to bearagainst the plate 0.

None of the parts of the sewing-machine are here shown, because theyform no part of this invention. My attachment can be applied to any orall sewing-machines, and for that reason no part of the sewing-machineproper need here be shown.

Having thus described my invention, I claim- I 1. In a machine forsewing on buttons,-a pivoted presser-foot which can be swung through aportion of a circle for the purpose of picking up a button, and which isprovided with means for holding the button, substantially as shown.
